Dual-Capacity System
A dual-capacity system is a distinct trading arrangement historically utilized on the London Stock Exchange (LSE), wherein the roles of stockbroker and stockjobber (or dealer) are distinctly separated into different firms. This system allows each entity to specialize in its respective function—brokers acting as agents for clients wishing to buy or sell shares, and jobbers dealing as principals with the brokers, thereby providing liquidity and setting prices. This construct was a cornerstone of the LSE until the seismic shift caused by the Big Bang in October 1986, which introduced a single-capacity system and allowed firms to combine these roles as market makers.
Historical Context and Implications
Prior to the Big Bang deregulation, the dual-capacity system ensured a clear division of responsibilities, minimizing conflicts of interest and fostering a competitive yet orderly market environment. Brokers were prohibited from holding inventories of securities, which guarded against market manipulation and excessive speculation. The introduction of the single-capacity system aimed at enhancing market efficiency by reducing transaction costs and improving transparency, yet it also raised concerns about potential conflicts of interest and the concentration of market power.
Humorous Insight
Imagine a world where your barber is also your baker. Confusing? Definitely—and potentially hairy bread! The separation in the dual-capacity system was akin to keeping barbers far from bakeries, ensuring each expert stuck to their knitting—or in this case, trading!
Advantages and Disadvantages
Advantages:
- Clearly defined roles reduced the potential for conflicts of interest.
- Enhanced market integrity by preventing brokers from acting as both buyers and sellers.
Disadvantages:
- Potentially less efficient than the more modern single-capacity system.
- Could result in higher costs for investors due to the need for intermediaries.
